welcome to the forum, where is "some places"

GM has confirmed, so do not go looking else where

Multiple dealers for wheels (tire rack and rimzone) as well as 2 GMC Dealers... but they seemed unsure. I tried going through GMC website but they referred me to dealers... who obviously gave me wrong info.

Does anyone have any links to these videos/discussions where it is mentioned/confirmed by GM?

Thank you.

Our data is indicating 6-139.7 as well, though we do not have complete O.E. wheel dimensions or stud size as of yet. I would imagine the lug hardware will remain 14x1.5, however the 1st gen did have 12x1.5.

Great, thank you!

Happy to help! When we learn more we'll be sure to share.

Any chance you have an idea of what the offset is?

I'm trying to see if I can run. A 285/70r17 on a -12mm offset.

My AT4 is coming with 275/60r20 (which is gross) so I think it's doable depending on offset.
